SAFETY INSTRUCTIONS

WARNING!
Read all the safety instructions and other instructions. Failure to follow all the instructions and safety instructions can result in the risk of electric shock, fire and/or serious personal injury. Save all warnings and instructions for future reference. The term “power tool” in all the warnings below refers to mains-powered (corded) or batterypowered (cordless) power tools.
WORK AREA

• Keep the work area clean and well lit. Dark and cluttered work areas increase the risk of accidents and injuries.
• Do not use power tools in explosive environments, such as in the vicinity of flammable liquids, gas or dust. Power tools produce sparks that can ignite dust and fumes.
• Keep onlookers, especially children, at a safe distance when using power tools. You can easily lose control of the power tool if you are distracted.

ELECTRICAL SAFETY

• The plug on the power tool must match the power point. Never modify the plug in any way. Never use an adapter with earthed power tools. Unmodified plugs and matching power points reduce the risk of electric shock.
• Avoid body contact with earthed surfaces such as pipes, radiators, cookers and refrigerators. There is an increased risk of electric shock if your body is earthed.
• Do not expose power tools to rain or moisture. There is a greater risk of electric shock if water gets into a power tool.
• Be careful with the power cord. Never use the power cord to carry or pull the tool, or to pull out the plug from the mains socket. Keep the power cord away from heat, oil, sharp edges and moving parts. Damaged or tangled power cords increase the risk of electric shock.
• If using the tool outdoors, only use an extension cord approved for outdoor use. Cords intended for outdoor use reduce the risk of electric shock.
• If it is absolutely necessary to use power tools in damp conditions, use a mains connection protected by a residual current device (RDC). Using an RCD reduces the risk of electric shock.

PERSONAL SAFETY

• Stay alert. Pay attention to what you are doing, and use your common sense when working with power tools. Never use power tools if you are tired or under the influence of drugs, alcohol or medication. A moment of inattention or carelessness can result in serious personal injury.
• Use personal safety equipment. Wear safety glasses or a visor. Depending on the type of tool and how it is used, safety equipment such as dust masks, non-slip safety shoes, safety helmets and ear protection reduce the risk of personal injury.
• Avoid accidental starting. Check that the power switch is in the OFF position before plugging in the plug or battery, or lifting/carrying the tool. Carrying a power tool with your finger on the switch or connecting a tool to the mains supply when the switch is in the ON position increases the risk of accidents and injuries.
• Remove adjuster keys/spanners before switching on the power tool. Spanners or the like that are left in a rotating part of the power tool can cause personal injury.
• Do not overreach. Always maintain a firm footing and good balance. This ensures better control over the power tool in unexpected situations.
• Wear suitable clothing. Do not wear loose-fitting clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose-fitting clothing, jewellery and long hair can get caught in moving parts.
• If dust extraction and dust collection equipment is available, this should be connected and used correctly. The use of such devices can reduce the risk of dust-related problems.

USING AND LOOKING AFTER POWER TOOLS

• Do not force the power tool. Use the correct power tool for the planned work. The tool does the job better and more safely when used at the rate for which it was designed.
• Do not use the power tool if it cannot be switched on and off with the power switch. Power tools that cannot be controlled with the power switch are dangerous and must be repaired.
• Pull out the plug and/or remove the battery before making any adjustments, changing accessories or putting the power tool away. These safety precautions reduce the risk of accidentally starting the power tool.
• Store power tools out of the reach of children when not in use. Never allow children, or anyone who is unfamiliar with the power tool and these instructions, to use the tool. Power tools are dangerous if used by inexperienced persons.
• Maintain power tools and accessories. Check that moving parts are properly adjusted and do not jam, and that no parts are incorrectly fitted or damaged. Check for other factors that could affect functionality. If a power tool is damaged it must be repaired before it is used again. Many accidents are caused by poorly maintained power tools. • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to jam and are easier to control.
• Use the power tool, accessories and bits etc., in accordance with these instructions, taking into account the actual working conditions and the work that is to be done. It can be dangerous to use power tools for purposes other than those for which they are intended to be used.
• Keep handles and grips clean, dry and free from oil and grease. Greasy handles and grips make it difficult to hold and control the tool in unexpected situations.

USING AND MAINTAINING BATTERY POWERED TOOLS

• Only charge the battery with the charger recommended by the manufacturer. Charging other batteries can result in a risk of personal injury and/or fire.
• Only use batteries recommended by the manufacturer. The use of other batteries can result in a risk of personal injury and/or fire.
• When the battery is not in use keep it away from metal objects such as paperclips, coins, keys, nails, screws and other small metal objects that can short circuit the terminals. Short circuiting discharges large amounts of energy that can cause a fire and/or burn injuries.
• Failure to handle the battery carefully can cause fluid to leak from the battery. Avoid contact with battery fluid. On contact with battery fluid, rinse immediately with plenty of fresh water. Seek medical attention if you get battery fluid in your eyes. Battery fluid can cause skin irritation and/or burns.
• Do not use damaged or modified batteries, or power tools that are damaged. Damaged or modified batteries can behave unexpectedly and cause a fire, explosion or risk of personal injury.
• Do not expose batteries or power tools to naked flames or heat. Batteries can explode when exposed to naked flames or temperatures higher than 130°C.
• Follow the instructions for charging and charge the battery only at the temperature indicated in the instructions.
  Incorrect charging or charging outside the given temperature range can damage the battery and cause a fire.

SERVICE

• Power tools must only be serviced by qualified personnel using identical spare parts. This will ensure that the power tool remains safe to use.
• Never attempt to repair damaged batteries. The battery must only be serviced by the manufacturer or at an authorised service centre.

SPECIAL SAFETY INSTRUCTIONS FOR CIRCULAR SAWS.

• All the warning symbols on the power tool must be clearly visible.
• Do not put anything on top of the tool. If the tool tips over or if you touch the saw blade this can lead to serious injury.
• Check that the blade guard is working properly and can move freely. Never clamp the guard open.
• Never attempt to clear away pieces of wood or sawdust from the saw while it is running. Put the saw arm in its rest position and switch off the tool with the power switch.
• Only apply the saw blade against the workpiece when the saw is running. Otherwise there is a risk of kickback if the blade jams in the workpiece.
• Keep the handles clean, dry and free from oil and grease. Greasy or oily handles are slippery and can cause you to lose control.
• Remove tools and sawdust from the workspace before sawing. Only the workpiece should be there. Small pieces of wood and other objects that come into contact with the rotating blade can be thrown towards the operator at high speed.
• Remove sawdust and other debris from the floor. You can slip on it or stumble.
• Always firmly secure the workpiece. It is safer to secure the workpiece with a clamp than to hold it with your hand. Do not saw workpieces that are not firmly secured. Otherwise your hand will come too near the rotating saw blade.
• Only use the power tool for the type of material it is intended for. Otherwise it can overheat.
• If the blade fastens, switch off the tool and hold the workpiece firmly until the blade has stopped rotating. To avoid kickback, do not attempt to loosen the workpiece before the blade has stopped. Find out why the blade has stuck and rectify the problem before using the tool again.
• Never use blunt, cracked, bent or damaged blades. Blades with blunt or skew teeth result in narrow cuts. This increases the friction, the risk of the blade getting stuck and the risk of kickback.
• Always use saw blades of the right size and with the right mounting hole (e.g. star-shaped or round). Blades that do not fit properly on the saw quickly lose their roundness and become difficult to control. Never use high-speed steel (HSS) blades. This type of blade breaks easily.
• Do not touch the blade after sawing until it has cooled. The blade gets very hot during the sawing.
• Never use the tool without the insert plate. If the insert plate is defective, replace it. A fault on the insert plate can result in an injury from the saw blade.
• Check the power cord at regular intervals. A damaged cord must be replaced by an authorised service centre. Replace the extension cord if it is damaged. This maintains safety.
• Always store the power tool safely. The storage space must be dry and lockable so that the tool is not damaged and so no unauthorised person can access it.
• Do not leave the tool unsupervised until it has come to a complete stop. Cutting tools that are still moving can cause injury.
• Do not use the tool if the power cord is damaged. Do not touch a damaged cord, and pull out the plug if the cord is damaged during the work. Damaged power cords increase the risk of electric shock.

ADDITIONAL SAFETY INSTRUCTIONS
Risk of kickback
Kickback can suddenly occur if the blade gets stuck, jams or is incorrectly adjusted. The saw then kicks up from the workpiece towards the user.

• If the blade jams, or gets caught in a cut that is squeezed together, it will lock and the power of the motor can cause the saw to kick back towards the user.
• If the blade is twisted, or comes out of alignment in the cut, the teeth on the back edge of the blade can cut into the surface of the workpiece, so that the blade jerks out of the cut and kicks back towards the user.

Kickback occurs when the saw is used incorrectly and/or with the wrong work methods, or in the wrong conditions, and can be avoided as follows.

• Hold the saw firmly with both hands and hold your arms in a position that prevents kickback. Stand to the side of the blade, not in line with it. Kickback can cause the saw to jerk backwards, but the user can control this by taking the appropriate measures.
  NOTE: “with both hands” does not apply to circular saws with a maximum blade diameter of 140 mm or less.

• If the blade jams or the sawing is interrupted for any reason, release the power switch and hold the saw still in the workpiece until the blade has completely stopped. Never attempt to remove the saw from the workpiece, or pull the saw back, while the blade is still moving – otherwise kickback can occur. Check and rectify the reason why the blade has jammed.

• When restarting the saw in the workpiece, centre the blade in the kerf and check that the teeth are not gripping the material. If the blade jams it can lift or kick back from the workpiece when the saw is started again.

• Support large boards to minimise the risk of kickback or the blade jamming. Large boards often sag under their own weight. Supports must be placed under the board on both sides, close to the cutting line and close to the edge of the board.

• Do not use blunt or damaged blades. Poorly sharpened or incorrectly adjusted blades produce narrow saw cuts, which generate excessive friction and cause the blade to jam or kick back.

• The locking devices for the depth and angle of the blade must be tightened and secured before you start working. If the adjustment of the blade changes during the sawing there is a risk of the blade jamming or kicking back.

• Take extra care when plunge cutting in walls or other similar areas where you cannot see what lies behind. The protruding blade may strike objects that can cause kickback.

Bottom guard

• Check before use that the bottom guard closes correctly. Do not use the saw if the guard does not move freely and immediately closes around the blade. Never lock or block the guard in the open position. The guard can be twisted if the saw is knocked. Lift up the bottom guard with the handle and check that it moves freely in all sawing depths and angles, and does not touch the blade or any other part.
  NOTE: Other designation for “handle” is possible.

• Check that the spring on the bottom guard works properly. If the guard and the spring do not function correctly they must be repaired before use. The bottom guard can get stiff as a result of damaged parts, tacky deposits or the accumulation of debris.

Additional instructions

• Do not use grinding discs.
• Only use blades with a diameter that corresponds to the markings on the power tool.
• When working in wood, or if the tool is used for materials that release toxic dust, the tool must be connected to a suitable dust extraction device.
• Wear a dust filter mask when working in wood.
• Only use saw blades recommended for the work.
• Wear ear protection.
• Avoid overheating the teeth on the blade.
• Watch out for the risk of melting the workpiece when sawing in plastic.

REDUCTION OF NOISE AND VIBRATIONS

• Plan the work so that exposure to heavy vibrations is spread over a longer period.
• To reduce noise and vibrations when in use, limit the time the tool is in use, and use low-power/vibration mode and suitable safety equipment.
• Take the following precautions to minimise the risks of exposure to vibrations and/or noise:
  – Only use the tool in accordance with these instructions.
  – Check that the tool is in good condition.
  – Use accessories in good condition, and which are suitable for the purpose.
  – Keep a firm grip on the handles/grips.
  – Maintain and lubricate the tool in accordance with these instructions.

LASER

• Do not look directly at the beam.
• Never point the laser beam at reflective surfaces, people or animals. Even low power laser beams can damage the eyes.
• Any deviation from the work method described here can result in a risk of dangerous exposure to radiation.
• Never open the laser module.
• It is not permitted to modify the laser in any way to increase the power of the laser.
• The manufacturer cannot assume liability for any damage resulting from failure to follow the safety instructions.

Always wear ear protection!
The declared values for vibration and noise, which have been measured according to a standardised test method, can be used to compare different tools with each other and for a preliminary assessment of exposure. The measurement values have been determined in accordance with EN 62841-2-5: 2015.
WARNING!
The actual vibration and noise level when using tools may differ from the specified maximum value, depending on how the tool is used and the material. It is therefore necessary to determine which safety precautions are required to protect the user, based on an estimate of exposure in actual operating conditions (taking into account all stages of the work cycle, e.g. the time when the tool is switched off and when it is idling, in addition to the start- up time).

HOW TO USE – PLUNGE CUT

1. Mark out the planned cut on the workpiece. Mark out with guide lines the start and endpoint of the cut. Both the cut line and guide lines on each side of the sole should stretch behind the back edge of the sole at the start of the cut and in front of the front edge of the sole at the end of the cut.
2. Place the saw on the workpiece. Align, with the cut line window (13) and the endpoint markings at the back end of the sole, the saw precisely to the cut line. The end of the blade guard is transparent, so a correctly aligned position can be verified. When permitted by the shape and size of the workpiece, the workpiece should be fixed with the supplied parallel fence or suitable fixing rail.
3. Move the saw straight towards the planned cut until the back marking on the sole (7) is in front of the guide line’s endpoint marking.
4. Start the saw.
5. Move the power switch lock (2) all the way to the side and hold it there. This releases the blade guard.
6. Lower the blade into the workpiece. Move the saw smoothly forward until the front marking on the sole (7) is in front of the guide line’s endpoint marking.
7. Switch off the saw. Wait until the blade has stopped and then lift it out of the workpiece.

HOW TO USE – SAWING

1. Mark out the planned cut on the workpiece.
2. Move the blade, without starting the saw, towards the workpiece. Align the blade with the help of the cut line window (13) and the laser. When permitted by the shape and size of the workpiece, the workpiece should be fixed with the supplied parallel fence or suitable fixing rail.
3. Start the saw.
4. Move the power switch lock (2) all the way to the side and hold it there. This releases the blade guard.
5. Press the saw blade down until the guard starts to open, but not so far that the blade touches the workpiece.
6. Move the saw smoothly forward and complete the sawing in one single stroke. Switch off the saw.

MAINTENANCE
